Our objective was to evaluate whether preterm birth (PTB) (<37 weeks) was associated with anesthesia type, anesthesia timing by trimester, or intervention. METHODS: We retrospectively identified pregnant patients who required surgical management with ureteral stent, percutaneous nephrostomy (PCN), or ureteroscopy (URS) for suspected renal colic based on laboratory and imaging findings from 2009 to 2021 at our academic tertiary care center. Analyzed data included anesthesia type (local analgesia only, monitored anesthesia care MAC, spinal anesthesia, or general anesthesia GA), trimester of procedure, procedure type, and obstetric outcomes including PTB. RESULTS: The study cohort included 98 pregnant patients who underwent 234 total procedures including primary URS, PCN, stent, as well as PCN and stent change. The most common anesthetic used across all procedures in all trimesters was MAC. For patients undergoing primary URS in the second trimester, GA and spinal anesthesia were used (50% and 50%, respectively). For patients undergoing URS in the third trimester, spinal anesthesia was the most common anesthetic used (71.4%). Similarly, stent placement in the second and third trimester was commonly performed under spinal anesthesia (38.7% and 53.1%, respectively). Conversely, PCN insertion or exchange was more likely to be completed under local anesthesia only or MAC during the second and third trimesters. Using multivariable logistic regression, intervention type was associated with PTB, but not anesthesia type or timing by trimester (Table 1). CONCLUSIONS: This study describes the type of anesthesia administered to women undergoing procedures for suspected renal colic during each trimester of pregnancy, and subsequent risk of PTB. PCN was associated with the use of less invasive analgesia or anesthesia, whereas endoscopic procedures were associated with GA or spinal anesthesia. Anesthesia type was not associated with PTB, and selection may be influenced by resources, clinical scenario, or patient and provider preferences.
